Nuclear theory sits at the fascinating intersection of particle physics and the forces that hold our universe together. This field explores how protons and neutrons bind inside atomic nuclei, seeking to understand the fundamental interactions that govern matter at its most dense and energetic levels. While the mathematics involved can be incredibly complex, the core questions are deeply human: how does the universe function at its smallest scales, and what happens when we push matter to its limits?

At Gist.Science, we make these cutting-edge discoveries accessible by processing every new preprint published in this category on arXiv. Our team transforms dense academic manuscripts into clear, plain-language summaries alongside detailed technical overviews, ensuring that both experts and curious readers can grasp the latest breakthroughs without getting lost in the jargon. Below are the latest papers in nuclear theory, distilled and ready for you to explore.

Gluon GTMD at strong coupling: fixed-spin saddle factorization and Reggeization

This paper utilizes gauge/string duality to construct conformal moments of unpolarized gluon GTMDs at strong coupling, demonstrating that these moments factorize into universal soft factors and stripped amplitudes while revealing how holographic backgrounds dictate infrared falloffs and enable a unified description of hadron tomography, rapidity evolution, and Reggeization relevant to the Electron-Ion Collider.

Evidence of the Excited X(5)-like Critical-Point Symmetry Structures in 152Sm

This study utilizes high-statistics gamma-ray spectroscopy of 152^{152}Sm to identify new excited collective bands and transition strengths that provide evidence for X(5)-like critical-point symmetry structures extending beyond the well-known low-lying spectrum, thereby offering new constraints on shape-phase transitions in the N=90 region.

Is the coexistence of strange quark stars and hadronic stars favored by astrophysical data? A Bayesian analysis

This paper presents a Bayesian analysis using astrophysical and laboratory data which finds that the two-families scenario, proposing the coexistence of hadronic and strange quark stars, is favored over the standard one-family model because it naturally resolves the tension between the soft equation of state required for small-radius objects and the stiff equation of state needed to support massive pulsars.

A short-range effective theory for single-neutron halo nuclei with a deformed core

This paper establishes a short-range effective theory for single-neutron halo nuclei with deformed cores, demonstrating that the leading-order particle-plus-rotor model accurately describes the low-lying spectra and Coulomb breakup observables of 11^{11}Be and 17^{17}C, while showing that regulator dependence in asymptotic normalization coefficients and dissociation cross sections is effectively resolved by including a single next-to-leading-order operator.

Hyperonic equation of state for neutron stars: A systematic Bayesian comparison of density-dependent and non-linear relativistic mean-field models

This study employs a systematic Bayesian analysis to compare relativistic mean-field models of dense matter, revealing that while the inclusion of hyperons consistently softens the equation of state and increases neutron star radii, all resulting models remain consistent with observed 2 M⊙2\,M_\odot mass constraints and suggest that specific mass-radius relationships could serve as evidence for hyperonic degrees of freedom.

Proton's isovector PDF with updated analysis of large-momentum lattice data

By applying state-of-the-art theoretical tools and empirically mitigating lattice artifacts to reanalyze existing large-momentum lattice QCD datasets, this study demonstrates that the proton's isovector parton distribution function is consistent with experimental global fits within approximately one standard deviation, validating the predictive capability of the large-momentum expansion approach.

Full Configuration Interaction Quantum Monte Carlo for Accurate Ab Initio\textit{Ab Initio} Nuclear Structure Calculations

This paper introduces full configuration interaction quantum Monte Carlo (FCIQMC) as a novel, accurate stochastic solver for ab initio\textit{ab initio} nuclear structure calculations, demonstrating its capability to compute ground-state properties of light nuclei with sub-percent uncertainties and treat systems beyond the reach of conventional methods.
